One of the hardest things to do in a job is to admit a mistake. Everyone is out to impress their manager and it can be tough to own up and risk your reputation. It can be beneficial as well though, giving you the opportunity to learn from what you have done. This is especially important in a career like teaching, where the work is challenging and you are working with people who are fully relying on you.
The first thing to do is to admit your mistake to yourself. If it isn’t going to impact anyone else’s career or education, you don’t necessarily need to own up. Just make sure you are aware of the mistake and can rectify it.
Next, think about what you might have done differently. Think it all through and learn as much as you can from it. This will help you to perform better in your role in future.
